West Coast speedster Jamaine Jones suffered a hamstring complaint in just his second match for the Perth-based club on Saturday.

Eagles coach Adam Simpson said the Heywood and Portland export was expected to spend one to two weeks on the sidelines.

West Coast captain Luke Shuey also limped from the field with a hamstring issue in the first term but the Eagles still managed a 34-point over Sydney.

Simpson suggested a testing training session midweek may have contributed to the pair's setback.

"We had some sore boys towards the end of the game," he said. "We were pushing a couple of buttons throughout the week to try and work out what was going on and might have pushed them pretty hard on Wednesday training."

Meanwhile, Princetown product Ben Cunnington was forced to the bench for the majority of North Melbourne's defeat to Western Bulldogs on Saturday night.

Cunnington copped a knock in the opening minutes and failed to recover as the Bulldogs cruised to a 49-point thumping.

Kangaroos coach Rhyce Shaw admitted it was "possibly the wrong call" to play Cunnington, who had been sidelined for a fortnight with back issues.

"(Cunnington) copped a knock early and then it just didn't get any better. He wasn't giving us anything from then on in, so it's really disappointing," Shaw said.

"He was in doubt all week, as we stated early in the week, and he got up and we were confident and I made a decision to play him, so that's where it sits.

"It possibly was the wrong call but we were really confident, to be honest, on all the evidence we were given ... I was really confident with the way he was going and he warmed up really well, so it's just what it is."
